From now on, there will only be four models offered for sale, all four models will have perfectly flat bases, they will all be supplied with lids and the standpipes have been dispensed with completely.

(To be honest, I’ve seen no real added improvements on using the collection troughs on my own units and to add this trough, only increases the price of the box and makes it more costly to transport).

The waste outlets to all units are centred at the base of the front face of the filter, access beneath the filter is no longer required

1. THE COMPACT FILTER – This is available to order in clear PVC or in polypropylene – either as a gravity-fed or a pump-fed unit. There will be a standard 2” ‘IN’ on this and a standard 1.5” outlet to waste – on the gravity-fed unit there will also be a 1” pick-up for the pump connection. No steel framework is required and no extra baffles for strength are required on this. The appropriate rubber connectors will be supplied free complete with pipe stubs but slide valves or ball valves will have to be purchased by the customer unless they wish me to supply at an extra cost.

2. THE E1 FILTER – This also will have no steel frame and no extra baffle for added strength. Again it will be available to order in both clear PVC and polypropylene plus the filter will be available as pump-fed or gravity-fed. The inlet will be 3” bore – unless 4” bore is specified at no extra cost. The standard waste outlet will be 1.5” bore and the pump connection for gravity-fed units will be 1.5” bore. The appropriate rubber connectors will be supplied free complete with pipe stubs but slide valves or ball valves will have to be purchased by the customer unless they wish me to supply at an extra cost.

3. THE E2 FILTER – This will have no steel frame but it will have an extra internal baffle for added strength. Again it will be available to order in both clear PVC and polypropylene plus the filter will be available as pump-fed or gravity-fed. The inlet will be 3” bore – unless 4” bore is specified at no extra cost. The standard waste outlet will be 1.5” bore and the pump connection for gravity-fed units will be 1.5” bore. The appropriate rubber connectors will be supplied free complete with pipe stubs but slide valves or ball valves will have to be purchased by the customer unless they wish me to supply at an extra cost.

4. THE E3 FILTER – This will have the two steel supporting frames but no extra internal baffles for added strength. Again it will be available to order in both clear PVC and polypropylene plus the filter will be available as pump-fed or gravity-fed. The inlet will be 3” bore – unless 4” bore is specified at no extra cost. The standard waste outlet will be 1.5” bore and the pump connection for gravity-fed units will be 1.5” bore. The appropriate rubber connectors will be supplied free complete with pipe stubs but slide valves or ball valves will have to be purchased by the customer unless they wish me to supply at an extra cost.

(Most people are already aware that the reasons for using rubber boots on the polypropylene units is to be able to get the polypropylene stubs linked to UPVC tube and fittings).

(Reasons for making the E3 the largest in the range is because any pond that contains more than this 7,500-gallon volume, usually has more than one bottom drain. If this IS the case then a 10,000-gallon system with two bottom drains would require 2 x E2 filters and a 15,000-gallon system with two bottom drains would require 2 x E3 filters).
